The Dynapac Touch A new series of pneumatic tyred rollers: CP224, CP224W and CP274 Dynapac presents a series of new pneumatic tyred rollers. CP224, CP224W (with wide base tyres) and CP274 which replace CP221 and CP271. These machines incorporate several new feartures that will enhance efficiency, serviceability, operator comfort and the end result. These machines have hydrostatic propulsion.

Unique characteristics – From the experts in road construction Performance Compaction Control Visibility Operator Comfort Environment Serviceability

To achieve the same ground pressure on front and rear tyres, Performance - balance It is easy to ballast the machine with four steel ballast weights which are placed in boxes under the “Dynapac” cover. Each ballast has a weight of 2000 kgs (4410 lbs). Balanced all the way To achieve the same ground pressure on front and rear tyres, the ballast is distributed evenly, whether water, sand or steel is used.

The CP224W with wide base tyres Performance The CP224W with wide base tyres   which causes less lateral movement of the particles than standard tyres.

Performance – displays & controls The display, which always follows the seat, give all vital working information to the operator such as, working speed, water level (option), fuel level, asphalt temperature (option), tyre pressure (only with air-on-the run)

Performance – displays & controls F&R-lever Driving direction is controlled with the F&R-leverand speed is controlled with the throttle pedal. The F&R-lever and throttle control make the machine stop and accelerate smoothly when changing driving directions.

Performance – brake system Brake cylinders Disc brakes Valve Brake pedal Dual circuit braking system The brake pedal works on two independent brake cylinders and two separate hoses control the brake valve. This means that if one of the brake cylinders or one of the hoses from cylinder to brake valve fail, you still have full braking capacity on the two disc brakes.

Performance Under 3 meters   Under 3 meters The CP224 and CP274 are under 3 meters in height with Rops or Cab, which enables easy transporting.

When working at high altitude (3 000 m/ 10 000 ft) the Cummins QSB Performance - engine When working on high altitude the Cummins QSB will automatically adjust the fuel pump and charge pressure to keep the power. High performance Modern low emission diesel engines Stage 3A are standard in all markets. When working at high altitude (3 000 m/ 10 000 ft) the Cummins QSB automatically adjusts the fuel pump and charges pressure to keep the power.

Asphalt temperature meter Performance – options Sprinkler back up pump If the ordinary pump breaks, you can easily switch over to the back up pump and continue your compaction work. Air on the run The rollers can be equipped with Air on the run, meaning that the operator can adjust wheel pressure during operation. Asphalt temperature meter Gives the operator information about the compaction condition; too cold asphalt gives less or no compaction efficiency. Too warm asphalt increases the risk for sticking and picking up asphalt.

Performance – options Foldable scrapers Cocoa mats The scrapers are easy to fold up for cleaning and will also avoid wearing during transport of the machine. Cocoa mats Cocoa mats give extra protection against picking up asphalt on the tyres and can also make it possible to use less water.

Edge compactor / joint cutter Performance – options  The edge compactor is used to improve the stability of the outer edge of the asphalt mat and prevent water from penetrating into the mat. It can also be used to improve the joint between two layers by compacting before jointing. The edge cutter is often mandatory to use on run ways for aeroplanes. 10–15 cm (4-6 inch) of the edge is cut off to improve the edge because the outer edge often got bad quality due to segregation. Edge compactor / joint cutter  A hydraulic controlled edge cutter with three different cutting discs is available.

24 volts give good cranking capacity Performance 24 volts gives very good cranking capacity for the starter but it is also a fact that all electronics works better with 24 than with 12 volts. Battery voltage 24 volts give good cranking capacity

Visibility Compaction Control Performance Operator Comfort Environment Serviceability

Visibility Excellent visibility  The Cab design, as well as the 4-post ROPS, minimizes obstruction of the operator’s field of view. External process mirrors (optional) make it easy to follow curb stones.

Operator Comfort Compaction Control Performance Visibility Environment Serviceability

Operators comfort Operator’s station Excellent operator’s platform with possibility to slide and rotate seat and steering module including display, throttle, foot brake, switches and F&R-lever.  Roller operators are often working long days and good ergonomics gets important. A pneumatic roller is working forward as much as backwards and the 180 degrees turnable seat and steering module makes it possible for the operator to be seated with one shoulder in each driving direction turning his head and neck as little as possible. The module can also be slided from side to side to give best visibility on each side.

Operator Comfort Display & lever Menus Steering The operator never has to stretch out to reach different handles or switches. The display is always in front of the operator since everything follows the seat and steering module both when sliding and turning. Menus The display and menus are very easy to read and use. It is also easy to change between metric and imperial values. Change menus by using the switches at the bottom of the display unit.   Steering The steering wheel can be tilted for best operator comfort.

Operator Comfort Cab  The spacious asymmetric cab can be equipped with Air Conditioning (AC) or Automatic Climate Control (ACC).

make it easy to climb up or down from the machine. Operator Comfort  The most common injuries amongst roller operators is a twisted or broken foot when stepping down from the roller. Well located steps are essential to prevent this kind of injuries. Well located steps make it easy to climb up or down from the machine.

The roller can be equipped with hydraulic bio-degradable oil Environment   No waste It is easy to drain hydraulic oil, engine oil and coolant liquid without any waste. The roller can be equipped with hydraulic bio-degradable oil

Environment– Cooling fans  The rollers can work in ambient temperatures up to 50 °C so for most markets the capacity is more than enough but also means that the cooling fans most of the time can run at a very low speed which gives a very low noise level and lower fuel consumption. Cooling fans Hydraulic and thermostat controlled cooling fans give lower fuel consumption and less noise.

Serviceability  Modularization will make it possible for service people to quickly learn about the whole range. A lot of modules are the same. From a spare and wear parts point of view, this means that the stock can be hold on a low level. Modularization Modularization makes it possible for service people to quickly learn about the whole range. From a spare and wear parts point of view, this means quicker service to the end-user.

Serviceability Water system  Large water tank, 415 litres (110 gallon) with two filling caps. There are three filters for the water; one strainer in the filling holes, one strainer close to the water pump and one strainer in each nozzle. Lockable filling caps available as option.

Serviceability   Alarm The operator or a service technician receives any alarm directly on the LCD screen.

Everything within reach Serviceability   Everything within reach Servicepoints, such as filters are easy to reach and replace.

Dynapac Compaction Analyzer for static compaction Tracking of how many passes done Tracking of the temperature The system tells you: Where you have been with the roller. How many times passes you have made. What was the asphalt temperature when you did your last pass The roller is shown as a symbol moving on the display changing the colour of the tracks depending on how many passes you have made. You get full documentation of the compaction work recorded and you can bring the info to the office with an USB memory and work with statistics and analysis there in case you do not want to do it directly on the roller. One computer can be used for several prepared rollers. It is easy to move it from one roller to another. Full documentation of the compaction work
